邮政编码识别

• 图像识别与处理笔记 —— 字符识别、邮政编码识别（10 月 8 日暂存）

• 2010 毕业设计

• 2005.3 毕业设计 / 2005.3 毕业设计

• OpenCV：裁剪 6 位数的手写邮政编码

汽车牌照识别

二值化阈值集中常用的选取方法：双峰（2-Mode）法，P 参数法，Otsu 法，迭代法。

大津法（OTSU 法或最大类间方差法）

假定一个阈值，方差越大，说明差别越大。

迭代法（最佳阈值法）

一些代码

• from https://github.com/wzh191920/License-Plate-Recognition

• 代码还可以 车牌检测与定位

• 代码还可以 PYTHON 实现车牌识别

• 使用 opencv 和 python 实现车牌区域提取

• opencv + python 车牌识别

• https://github.com/DataXujing/vehicle-license-plate-recognition

案例分析

toP61-1 手写数字识别

toP58-2 邮政编码识别

toP60-3 汽车牌照识别

toP62-4 条形码识别

toP63-5 印刷体汉字识别

toP54-6 人脸识别

toP57-7 细胞识别与统计

toP55 SAR 图像分割 / 遥感图像配准

谱聚类（求解规范化 Laplace 矩阵的特征值和特征向量）

toP56/59 总变差（TV）模型 · 图像恢复

图象恢复是一个客观过程，需要利用 某些先验知识从退化和干扰的图像中去除模糊因素和噪声、尽可能恢复图像的本来面貌 。复原技术一般是先把 退化和干扰模型化 ，然后采用相反的过程进行处理，复原图像。
